So I went and bought an Apple MBPr from a Pawn Shop downtown, and it is in top condition. I want to wipe it clean, so I rebooted and held CMD-R. Long behold, there's a Lock logo with a password entry. I tried entering the password to the computer (which I set), and it didn't work.


Did a little reading online, and tried rebooting into targetted disk mode, and now it always boots to that lock. Can't even login to the computer regularly.


Please help me reformat my disk! Thank you!
